Lego soon on the moon

Scientists at the European Space Agency (ESA) are using Lego-like bricks to develop models for astronaut accommodation on the moon. These models are based on so-called ESA space bricks, which consist of 3D-printed meteorite dust. There is only a very small amount of the space material regolith on Earth. The team therefore uses meteorite dust. This is mixed with polylactide and regolith simulant and processed in 3D printers to create building elements that resemble Lego bricks. The aim of this initiative is to test different construction methods for the Artemis programme, which plans to return humanity to the moon.

Aidan Cowley, ESA Scientific Advisor, explains: "My team and I love creative building and we had the idea to explore whether space dust could be moulded into a brick that resembles Lego bricks so that we could test different building techniques. The result is amazing and although the bricks look a little rougher than usual, the clamping force still works, allowing us to playfully test our designs."

The combination of everyday materials and scientific innovation shows how versatile the principle of Lego bricks can be used. In my opinion, it is impressive how these simple building blocks can contribute to solving complex problems in space travel. Such projects illustrate the importance of interdisciplinary approaches in modern science and how they can lead to significant progress.

The Space Bricks will be on display in selected Lego stores worldwide until 20 September 2024. In Europe, you can see the bricks in the following cities: Cologne, Munich, Paris, London, Amsterdam, Copenhagen, Billund and Barcelona. <p
